I have an 07zafira and need a new bonnet
where would i find the code for the exsact match of paint? I was told it was inside the door but there are alot of numbers there which would it be? TIA

1/. Open door.

2/. Take high res. pic. of numbers on plate.

3/. Take this to paint shop.

Or ring the original supplying dealer with the reg. They will have the code on file.
